2021-09-28selftests/bpf: Switch SEC("classifier*") usage to a strict SEC("tc")Andrii Nakryiko1-1/+1
Convert all SEC("classifier*") uses to a new and strict SEC("tc") section name. In reference_tracking selftests switch from ambiguous searching by program title (section name) to non-ambiguous searching by name in some selftests, getting closer to completely removing bpf_object__find_program_by_title().

2021-03-26bpf: selftests: Add kfunc_call testMartin KaFai Lau1-0/+42
This patch adds a few kernel function bpf_kfunc_call_test*() for the selftest's test_run purpose. They will be allowed for tc_cls prog. The selftest calling the kernel function bpf_kfunc_call_test*() is also added in this patch.
